Can't Remote Desktop

There are many reasons why you can't remote desktop to a PC, but if you notice that you can remote desktop to a computer from location A, but NOT location B, then check your Windows firewall group policy for your remote desktop policy. You can restrict which subnets will accept remote desktop messages from at Computer Configuration | Administrative Templates | Network/Network Connections/Windows Firewall/Domain Profile.

Stale DHCP Reservation

When I tried to PXE boot a test PC, I couldn't get a DHCP address because there this PCs MAC had a duplicate DHCP reservation. The error I got was "ProxyDHCP service did not reply to request on port 4011". Removing the DHCP reservation for this MAC solved the problem. Thankfully, Windows 2003 Server DHCP labelled the reservation BAD_ADDRESS for me.

SMTP Delay

Users were getting a 30 second delay in starting their SMTP connection to our Plesk qmail service due to an rDNS lookup . To eliminate this delay, I followed a suggestion from a Plesk forum, added the -R switch to NOT obtain TCPREMOTEINFO from the remote host (refer to the tcp-env manpage) . I also had to remove the relay check to relays.ordb.org (removed -r relays.ordb.org ).

In summary, in /etc/xinetd.d/smtp_psa, I changed
server_args = /usr/sbin/rblsmtpd -r relays.ordb.org ...
to
server_args = -R /usr/sbin/rblsmtpd /var/qmail/bin/relaylock ...

Bad Yahoo Toolbar, Bad!

A user was getting an application error when quitting from IE7. I ended up fixing the problem by disabling Yahoo! toolbar. I've also subsequently uninstalled it as well.

Automatic login to Windows XP

Don't you like typing your password in to your personal computer that no one else uses? To automatically log in to Windows XP, run "control userpasswords2".

DAFT RAT (watermark is missing letters)

If your watermark is missing letters (such as a DRAFT comes out as DAFT or RAT), uncheck the semitransparent option in Format > Background > Printed Watermark .

Compile Error in Hidden Module: AutoExec

Upon opening MS Excel, I was getting a Visual Basic error ==> Compile Error in Hidden Module: AutoExecNew and upon exit ==> Compile Error in Hidden Module: DistMon.

I tried the solutions on Experts Exchange , but the solutions didn't work. My particular problem had to do with a user who had just moved computers. Her old computer had Adobe Acrobat, and her new one didn't. It seems that her old computer created some VB code in a roaming profile for this user. So, from within her login, I uninstalled Acrobat from the old computer and the errors disappeared from her new computer.

Instead of Acrobat, try PDF Creator.
